Apollo field exploration science, and subsequent analysis, and interpretation of its findings and collected samples, underpin our current understanding of the origin and history of the Moon. That understanding, in turn, continues to provide new and important insights into the early histories of the Earth and other bodies in the solar system, particularly during the period that life formed and began to evolve on Earth and possibly on Mars. Those early explorations also have disclosed significant and potentially commercially viable lunar resources that might help satisfy future demand for both terrestrial energy alternatives and space consumables. Lunar sortie missions as part of the Vision for Space Exploration provide an opportunity to continue and expand the human geological, geochemical and geophysical exploration of the Moon. Specific objectives of future field exploration science include: (1) Testing of the consensus "giant impact" hypothesis for the origin of the Moon by further investigation of materials that may augment understanding of the chondritic geochemistry of the lower lunar mantle; (2) Testing of the consensus impact "cataclysm" hypothesis by obtaining absolute ages on large lunar basins of relative ages older than the 3.8-3.9 Ga mascon basins dated by Apollo 15 and 17; (3) Calibration of the end of large impacts in the inner solar system; (4) Global delineation of the internal structure of the Moon; (5) Global sampling and field investigations that extend the data necessary to remotely correlate major lunar geological and geochemical units; (6) Definition of the depositional history of polar volatiles - cometary, solar wind, or otherwise; (7) Determine the recoverable in situ concentrations and distribution of potential volatile resources; and (8) Acquisition of information and samples related to relatively less site-specific aspects of lunar geological processes. Planning for renewed field exploration of the Moon depends largely on the selection, training and use of sortie crews; the selection of landing sites; and the adopted operational approach to sortie extravehicular activity (EVA). The equipment necessary for successful exploration consists of that required for sampling, sample documentation, communications, mobility, and position knowledge. Other types of active geophysical. geochemical and petrographic equipment, if available, could clearly enhance the scientific and operational return of extended exploration over that possible during Apollo missions. Equipment to increase the efficiency of exploration should include the following, helmet-mounted, systems: (1) voice activated or automatic, electronic, stereo photo-documentation camera that is photometrically and geometrically fully calibrated; (2) automatic position and elevation determination system; and (3) laser-ranging device, aligned with the stereo camera axis. Heads-up displays and controls on the helmet, activated and selected by voice, should be available for control and use of this equipment.
